DUMPING-CAR.

Specification of Letters Patent.

Application filed May 5, '1909.

Patented Mar. 8, 1910. serial Nol/194,148.

To all whom it may concern:

Be it known that I, CHARLES RUSSELL, WI-rrrrnn, a citizen of the United States, residing at Worcester, in the county of VVorcester and State of Massachusetts, have invented certain new and useful Improvements in Dumping-Cars, of which the following is a specification.

This invention relates to improvements i side dumping cars, and the object in view is the enabling of simultaneous or independ` ent dumping of one or more of the cars composing a train while providing efficient retaining means for the side doors previous to dumping.

With this and further objects in view as will in part become obvious and in part be set forth, the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter disclosed and claimed.

In the accompanying drawings z-Figure 1 is a plan view of a car embodying the fe`a`` tures of the present invention, a portion of the car body being broken away to disclose the sub-structure. Fig. 2 is a side view thereof. Fig. 3 is a transverse vertical section taken on the plane indicated by line 3 3 of Fig. 1. Fig. 4 is a fragmentary side elevation on an enlarged scale. Fig 5 is ay transverse section through a fragment of` the car showing the clamps in open position. Fig. 6 is a horizontal section taken on the plane indicated by line 6 6 of Fig. 3. Fig. 7 is a detail fragmentary view of the rock shaft gripping device for one of the clamps.

Referring to the drawings by numerals, 1, 1 indicate center sills of the built up I- beam trussed construction, as clearly seen in` Fig. 2. Bolted or otherwise suitably fixed to each of the beams 1, and rising from the upper cover plate thereof are upstanding journal brackets 2, 2, each terminating at its upper end in a journal bearing or sleeve 3. The brackets 2 are spaced apart at any suitable intervals. Journaled inthe bearings 3 above each I-beam 1, is a rock shaft 4 which may be of any desired dimensions, and preferably extends throughout the greater part of the length of the beam. At suitable intervals along the length of each rock shaft 4, clamp bars 5 are attached. Each bar5 terminates at its inner end in a Usuitable grip device 6 adapted to aord al rigid connection with the respective shaft 4. Each grip device 6 may be made up of a semi-circular block bolted to the end of the bar 5, which end is formed with an integral semi-circle, the meeting semi-circles being of a size adapted to snugly receive and grip the respective shaft 4. The outer end of each bar 5 is provided with an upturned hook 7, the inner edge 7 of which is formed on a bevel for the purposes hereinafter stated. Intermediate the length. of the beams 1, the same are connected by a cylinder supporting plate 8 upon which is mounted air or other fiuid pressure cylinders 9, 9,

`adapted to be supplied with fluid pressure through train pipe 10. Branch pipes 11, 11, extending from the pipe 10 to the respective cylinders, are provided each with a stop `cock or valve 12 engaged by an operating `rod 13 extending to the respective side of the car o poslte to that controlled by the given cylin er. The piston 14 of each cylinder 9 is pressed by spring 15 for normally maintaining the head of the piston at the inner end of the cylinder, the piston rod 14 ex tending beyond the cylinder and being pivotally connected with a crank arm 16 fixed vto the respective rock shaft 4 so that when pressureis admitted to a given cylinder, the piston will be thrown and the shaft 4 rocked in a direction for swinging the clamp bars 5 downwardly. Obviously, when the pressure is exhausted from the cylinder and the spring 15 is allowed to cause a return movement of the piston, the shaft 4 will be correspondingly given a return movement elevating the clamp bars 5 to their raised position.

Fixed to each I-beam 1, and extending outwardly therefrom are angle brackets 17, 17 which are inclined outwardly and support the inverted V-shaped hopper' bottom 1S of the car. The car is of course provided `with the usual `end plates 19 and side plates `2O, the side plates20 terminating at a suitable distance above the lower edges of the same transverse planes of the car with the` corresponding clamp bars 5 and positioned to receive the hooks 7 thereof. Vithin each staple 23 is arranged a cam block 241 which may be fixed in place in any preferred manner as by being riveted or otherwise suitably secured to the outer face of the door 21. The outer edge of each block 24 is beveled or curved to correspond withthe bevel 7 so that as the upper end of the hook T enters one of the staples 23 the beveled portion thereof engages the beveled edge of the block 24 and wedges the door 21 inwardly until the clamp bar 5 has risen to its uppermost position, whereat the door 21 will be closed under a clamping pressure which will tend to retain the parts against accident-al separation and which will insure against springing of the door outwardly.

The operation will be obvious from the foregoing, and the same may be briefly 'stated as follows: Assuming a train load to be positioned for being dumped, it is only necessary for the operator to admit pressure to pipe 10, whereupon all of the clamp bais 5 throughout the entire train will be rocked downwardly and the doors 21 thus released.

The lateral component of the vertical stress of the load will throw open the doors, and the inverted V-bottom 18 will cause the load to be quickly and completely discharged. After the discharge of the load, the doors 21 are automatically closed, that is swing by gravity to the vertical closed position, and the pressure is exhausted from the operating cylinders 22 for allowing the clamping bars to return to the locked position. If at any time it becomes desirable to dump a load only at one side of the car, the valve 12 of the cylinder controlling the other side will be closed, and thus when pressure is admitted to pipe 10, the bars 5 at one side of the car only will be lowered. Or if found desirable, both valves 12 may be closed on some of the cars, and the corresponding valves on other cars being left open, will enable dumping of some of the cars without dumping those cars having closed valves.

Vhat I claim is,-

1. In a dumping car, the combination with a car structure having a side door, of a rock shaft extending longitudinally of the car, means for sustaining said shaft, a plurality of clamp bars connected to the shaft and adapted to be swung vertically thereby, a hook carried by each clamp bar adapted to extend outside said door when the bar is in its raised position, and means for rocking said shaft for lowering said clamp bars.

2. In a dumping car, the combination with a car body having a hinged side door and an under sill, of a rock shaft having a journaled connection with said sill and ex tending longitudinally of t-he car body, a

clamp bar fixed to said rock shaft and extending at right angles thereto, door engaging means carried by said clamp bar and adapted to engage the car door for retaining the same closed, and means for oscillating said rock shaft.

3. In a dumping car, the combination with a car body having vertically swinging side doors and under sills, of upstanding brackets carried by said sills having bearing sleeves, a rock shaft journaled in the bearing sleeves of each respective under sill, clamp bars fixed to each rock shaft and hextending outwardly toward the respective contiguous side of the car, door engaging means carried by the outer end of each clamp bar adapted to engage and retain the door in a closed position, and means for oscillating said rock shafts.
